booting ipxe from pxelinux

[jwm77]

I cannot believe that gpxecmd.c32 will solve my problem.
Maybe my description was to generic.

Up to syslinux 4.04 the following default. file worked fine.

#Default.
DEFAULT menu.c32
LABEL nfw
KERNEL ipxe.krn dhcp && chain http://10.10.10.10/NFW.ipxe

I could boot ipxe and transfer the commandline in one statement. Embedding commands in ipxe via "make" was not necessary.

Since syslinux 6.01 I get an error: invaldi argument.

How can I boot ipxe.lkrn or ipxe.pxe and supply parameters without engaging dhcp or embed them in ipxe during building ipxe?
